Carlo Alberto Biffi obtained a Master's degree in Mechanical Engineering in 2005 (thesis: “Modeling of heat source in deep penetration laser welding”) and a PhD in 2009 from the Mechanical Department at Politecnico di Milano, focusing on the topic of “Microdrilling of titanium with pulsed fiber laser: characterization of the process and reduction of spatter”. Since 2009, he has been a researcher at the National Research Council of Italy (CNR). His main research focuses on the investigation of the correlation between advanced processes, mostly laser material processing (welding, drilling, cutting, surface modification, thermal treatments, and additive manufacturing), and microstructure/functional properties of advanced materials, such as titanium, nickel-titanium, and biodegradable alloys. Since 2018, he has been part of the technical committee of “Metallurgia delle Polveri e Additive Manufacturing” of AIM (Italian Association of Metallurgy. Since 2010, he has been a professor under contract for a course on advanced manufacturing processes (from 2010 to 2014: “Unconventional Machining”; from 2015 to now: “Advanced Manufacturing Processes”) at Politecnico di Milano—Lecco Unit. He is responsible for some scientific and industrial projects sponsored by public and private foundations. He has been supervisor and co-supervisor of some Master's degree theses at Politecnico di Milano. He has co-authored more than 150 peer-reviewed papers indexed in Scopus (H index=29).
